This Metasploit module attempts to gain root privileges on Linux systems by abusing a vulnerability in the GNU C Library (glibc) dynamic linker with libmemusage.so library.
82d002207d92e79c81d147d0cbc73594This Metasploit module attempts to gain root privileges on Linux systems by abusing a vulnerability in the GNU C Library (glibc) dynamic linker. glibc ld.so in versions before 2.11.3, and 2.12.x before 2.12.2 does not properly restrict use of the LD_AUDIT environment variable when loading setuid executables. This allows loading arbitrary shared objects from the trusted library search path with the privileges of the suid user. This Metasploit module uses LD_AUDIT to load the libpcprofile.so shared object, distributed with some versions of glibc, and leverages arbitrary file creation functionality in the library constructor to write a root-owned world-writable file to a system trusted search path (usually /lib). The file is then overwritten with a shared object then loaded with LD_AUDIT resulting in arbitrary code execution. This Metasploit module has been tested successfully on glibc version 2.11.1 on Ubuntu 10.04 x86_64 and version 2.7 on Debian 5.0.4 i386. RHEL 5 is reportedly affected, but untested. Some glibc distributions do not contain the libpcprofile.so library required for successful exploitation.
2bf9e1106acf9e1f0a7b618fe7f2da3fSome distributions make virtfs-proxy-helper from QEMU either SUID or give it CAP_CHOWN fs capabilities. This is a terrible idea. While virtfs-proxy-helper makes some sort of flimsy check to make sure its socket path doesn't already exist, it is vulnerable to TOCTOU. This exploit should spawn a root shell, eventually, on vulnerable systems.

00ab722f2ba1b1ee134371e96d761d4aThis is the Mempodipper local root exploit for Linux. /proc/pid/mem is an interface for reading and writing, directly, process memory by seeking around with the same addresses as the process's virtual memory space. In 2.6.39, the protections against unauthorized access to /proc/pid/mem were deemed sufficient, and so the prior #ifdef that prevented write support for writing to arbitrary process memory was removed. Anyone with the correct permissions could write to process memory. It turns out, of course, that the permissions checking was done poorly. This means that all Linux kernels greater than and equal to 2.6.39 are vulnerable.
